Abstract
The valve has a chamber (11) in a housing (10), wherein a valve seat (17) closed by a valve body (19) is arranged. The valve seat (17) is abruptly moved by an actuator (15), the valve body (19) not being able to follow due to its inertia and the valve seat (17) being opened a little. Thereafter, the valve body (19) hits a plunger (20) moved by the actuator (15) together with the valve seat (17). By this impact, the valve body (19) is moved fully off from the valve seat (17) so that the outflow opening (13) is cleared entirely. Then, the flow drives the valve body (19) back into the closed position. Using this valve, short switching periods with a large valve opening degree may be achieved.
